It’s not the franchise owner or the chain, it’s the employee and yes that employee should he out of work. If the employee was terminated then the boycott is childish and punitive. It is nigh impossible to control what an employee does unless the owner/management is right at their shoulder every second. What business in their right mind would have a policy of alienating the very people they depend on for protection?
Also, as every New Yorker knows, police are the main customers of D&D! I’ve never seen one in a Starbucks (not that I use them all that much.)
